I've been hearing this since 2000-s and the price for wind did come down. But the cost of offshore generation also is not coming down. There's a reason for this - sea is a hostile environment and turbines have to be built to withstand much more aggressive weather.
The main problem with renewables right now is lack of energy storage, so simply scaling variable sources doesn't work at all. It's looking to be a fundamental problem that can derail the whole transition.
